That would be the Sea Lampreys
A.Lampreys
Answer:
Most animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates.
Explanation:
Role of decomposer in fooe chain/food web
Decomposers are organisms which convert complex organic molecules into their simple forms.
Example
bacteria, fungi etc.
Explanation
food chain stary from autotrophs and end at decomposers. these organisms are present in soil, rely on dead bodies of plants and animals for their nutrient requirements. These organisms possess strong enzymatic system, which scavenge comples molecules from dead bodies during respiration and convert them into simple nutrients which return back to atmosphere.
In this case, the unconditioned stimulus is; Chemotherapy.

Chemotherapy causes various side-effects (as a result of the damage of normal cells of the body that rapidly increase). Nausea with vomiting, are common side effects that is usually experienced by cancer patients that are receiving chemotherapy.
Answer:
purine
Explanation:
Purines are nitrogenous base that have two carbon-nitrogen rings. The most naturally occurring purines are adenine and guanine which are found in DNA and RNA as nucleotide building blocks of these polymers. Purines are constituents other important biomolecules, such as ATP, GTP, cyclic AMP, NADH, and coenzyme A. Purine and pyrimidine ribonucleotides built up essential intermediates in the synthesis of the polynucleotides RNA and DNA.
